I'll play too
Here's my Supermag project as of today. Knoxx Specops stock, 18 3/4" VR barrel. This whole project was centered on the awesome 3.5" 18-pellet 00Buck load. It certainly is an awesome stopper either on man or beast. Next move may be a extended mag. It will need a different fore end too. I think no optics on this one. Simple is better. Even with the Knoxx recoil reducing stock, it still packs a punch.
